HERBERT O. DUNN, OF VASHINGTON, DISTRICT OF COLUMBIA.

ANCHOR.

SPECIFICATION forming part of Letters Patent No. 395,429, dated January 1, i889.

Application filed June l, 1888. Serial No. 275,784. (No model.)

To all 11171/0711j it may concern:

Be it known that I, HERBERT Q. DUNN, a citizen ol' the United States, residin at llf'aslr ing-ton, in the District of Columbia, have invented a New Anchor, ot which the tollmving is a specification.

My invention relates to the kind of anchors having movable lnkes, and its object is to simplify the construction and improve the efficiency of such anchors, and at the same time insure quick biting or taking power ol the tinkcs. In addition it prevents the loss ot any part ot the anchor should the axial bolt or pin be broken in actual use. l attain these objects by the. mechanism illustrated in the accompanying drawings, in which- Fignre l is an elevation of the shank A A, with a cylindrical opening, D, for the pin ot' the anchor-shackle, and a cylindrical opening, C, through which passes the axial bolt P P, Figs. 4 and 5, which connects the combined crown lfl H and linkes li l, ol the anchor to the shank.

Fig. 2 is a plan olf the shank, showing the tapering enlargement ol' the head at a a. This shank is placed through the central longitudinal opening in the crown l-l ll, Fig. 5, from the crown end ot' the anchor, and is prevented from being pulled ont, should the axial bolt break, by diminishing` the size of the opening on the fluke side, as shown in Fig. 4 at a` a.

Fig. 3 is an elevation of the anchor, showing the anchor in its position when in aetion. P is the axial bolt or pin connecting the shank A A to the crown H H and iiukes B. The crown or head of the anchor is made in one piece with the dukes B B, Fig. 4, and the opening between the .dukes and through the crown is so cutaway on the linke side that the shank A A abuts against the inside, taking the strain in weighing the anchor, and preventing the linkes from making more than 'fifty degrees angle with the shank. The linkes B B, together with the crown l-l H, turn on the axial bolt P to Iifty degrees each side of the longitudinal line of shank A A and insure the engagement of the tlukes whichever side the anchor falls on.

Fig. 4 is a horizontal plan of the anchor,

showing the spread of the linkes B B, which -aXial bolt P P, which. connects the crown and shank.

As the figures show, the principal weight of this anchor .is in the crown, which, with the spread ot the dukes and the concave snrface f t, Fig. 3, insures certain and quick engagement of the linkes.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-m ln an anchor having a crown-piece integral with two spread flukes containing a longitudinal opening contracted on the fluke side, ashank with an enlarged tapered head containing a transverse cylindrical opening, said shank passing through the opening in the crown-piece, in combination with an axial bolt passing transversely through the shank-head and crown-piece, connecting the two, and allowing lukes to actuate each side of the shank, substantially as specified.

2. ln an anchor having a crown-piece integral with two spread iiukes containing a longitndinal opening shaped to t a tapered shank-head and contracted on the fluke side, a bolt or pin, in combination with a shank having an enlarged tapered head containing a transverse cylindrical opening, said shank passing through the crown-piece and connected thereto by said bolt passing transversely through the crown-piece and shankhead, allowing angular motion, substantially as set forth.

3. In an anchor having an enlarged headed shank containing a transverse cylindrical opening for axial bolt, a crown-piece integral with two spreading nukes containing a longitudinal slot or opening allowing shank-head IOO to aotnate, in combination with an axial bolt, Signed at Vasliington, in the District oi' So that the shank has angular motion each Columbia, this 251th. day of May, 1888.

sides of iinkes, said slot or opening being` con- H O DUNN tractecl between the shoulders of the flnkes 5 and preventing detachment of shank in case litnessesr of removal of axial bolt, substantially as XV. S. SCHLEY,

specified and set forth. G. XV. DEUFELD.
